National Mfg N222-141 Zinc U-bolt 5/16x1-3/4x3 in

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N222-141 is a 522-series zinc-plated U-bolt designed for pipe, conduit, and structural fastening applications. The U-bolt measures 5/16 inches in rod diameter, 1-3/4 inches in inside width, and 3 inches in inside height. The zinc plating provides corrosion resistance suitable for general indoor and light outdoor use. This hardware fastener is installed by plumbers, electricians, pipefitters, and general contractors where a reliable saddle-style clamp is required to secure round pipe or tubing to a flat surface.

This U-bolt is suited for residential and light commercial installations. Typical applications include securing water supply lines, conduit runs, and small-diameter pipe to framing, strut, or structural steel. Sold in a package quantity of 5, it is well suited for service techs and contractors who need a small quantity on hand for routine pipe support work.

Key Features

• 522-series zinc plating for corrosion resistance in general service environments
• Rod diameter of 5/16 inches for moderate load-bearing capacity
• Inside width of 1-3/4 inches accommodates standard pipe and conduit sizes in that range

Compatibility

Designed as a general-purpose OEM-style zinc U-bolt for securing round pipe, conduit, or tubing to flat mounting surfaces in plumbing, electrical, and mechanical installations.

Installation Notes

Install using appropriately sized nuts and washers to seat the U-bolt evenly against the pipe or conduit. Power down electrical systems or shut off water supply before working on live conduit or pipe runs. Follow applicable IPC, IFGC, or NEC guidelines for pipe and conduit support spacing. Do not overtighten, as excessive torque can deform thin-wall pipe or conduit.
